A reaction appears.

MgH2는 대표적인 금속수소화물로서, 다른 수소화물(hydride)보다 단위 질량당 수소 저장량이 높은 장점(수소저장밀도 7.8wt%)이 있다.MgH 2 is a representative metal hydride, and has the advantage of having a higher hydrogen storage amount per unit mass than other hydrides (hydrogen storage density of 7.8 wt%).

하지만, MgH2와 같은 금속수소화물은 수소 방출 반응이 일어나는 온도가 높고, 가열에 필요한 전력 소모가 크기 때문에, 수소 저장시스템의 열효율을 높이는 방안이 필요한 것은 물론, 시스템의 경량화를 위해 효율적인 열교환기 설계도 필요하다.However, since metal hydrides such as MgH 2 have a high temperature at which the hydrogen emission reaction occurs and the power consumption required for heating is large, a plan to increase the thermal efficiency of the hydrogen storage system is required, as well as an efficient heat exchanger design diagram for lightening the system. need.

본 발명의 바람직한 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1 및 도 2를 참조하여, 본 발명의 고체수소저장 장치에 대해 설명하면, 원통형의 저장용기(40) 내부에 그 축방향을 따라 다수의 열교환튜브(20)가 구비된다.Referring to FIGS. 1 and 2, when the solid hydrogen storage device of the present invention is described, a plurality of heat exchange tubes 20 are provided in a cylindrical storage container 40 along the axial direction thereof.

여기서, 상기 열교환튜브(20)는 금속재질의 가열튜브(20a) 및 냉각튜브(20b)를 포함하는 것으로, 상기 가열튜브(20a) 및 냉각튜브(20b)가 저장용기(40)의 축을 중심으로 임의의 반경 위치에 규칙적인 각도를 이루어 다수 구비된다.Here, the heat exchange tube 20 includes a heating tube 20a and a cooling tube 20b made of metal, and the heating tube 20a and the cooling tube 20b are centered on the axis of the storage container 40. It is provided in a number of regular angles at any radial position.

아울러, 수소가 저장 및 방출되는 수소저장소재(30)는 MgH2, NaAlH4 등과 같은 금속수소화물로서 원반형의 형상으로 다수 형성되어 상기 저장용기(40) 내부에 구비된다. 이때에, 상기 수소저장소재(30)에는 상기 열교환튜브(20)와 대응하는 위치에 관통홀(31)이 형성되어, 상기 열교환튜브(20)가 관통 구비됨으로써, 상기 열교환튜브(20)로부터 열이 공급될 수 있게 된다.In addition, the hydrogen storage material 30 in which hydrogen is stored and released is formed in a plurality of disk-shaped metal hydrides such as MgH 2 , NaAlH 4, etc., and is provided in the storage container 40. At this time, the hydrogen storage material 30 has a through hole 31 formed at a position corresponding to the heat exchange tube 20, and the heat exchange tube 20 is provided through it, so that heat from the heat exchange tube 20 Will be able to be supplied.

그리고, 서로 이웃하는 두 개의 수소저장소재(30) 사이에는 열교환튜브(20)에서 수소저장소재(30)에 전달되는 열전도율 향상을 위해 열전도 성능이 우수한 열전달핀(10)이 각각 구비된다.In addition, heat transfer fins 10 having excellent heat conduction performance are provided between the two adjacent hydrogen storage materials 30 to improve the thermal conductivity transferred from the heat exchange tube 20 to the hydrogen storage material 30.

이를 위해, 본 발명에 따른 열전달핀(10)은, 상기 열교환튜브(20)가 관통되도록 상기 열교환튜브(20)와 대응하는 위치에 튜브관통부(11)가 각각 형성되고, 상기 튜브관통부(11)들이 선 형상의 연결부(13)에 의해 연결되는 구조가 된다.To this end, the heat transfer fin 10 according to the present invention has a tube through portion 11 formed at a position corresponding to the heat exchange tube 20 so that the heat exchange tube 20 penetrates, and the tube through portion ( 11) has a structure in which they are connected by a linear connection part 13.

이에, 상기 튜브관통부(11)들을 잇는 연결부(13)들에 의해 연결부(13)들 사이에 폐공간(S)을 이루게 된다.Accordingly, a closed space (S) is formed between the connection parts 13 by the connection parts 13 connecting the tube through parts 11.

즉, 기존에는 상기 열전달핀(10)이 평판의 디스크 형상으로 형성되어 튜브관통부(11)들의 열이 전달되도록 구성되는 반면, 본 발명에서는 선 형상의 연결부(13)에 튜브관통부(11)들이 이어지도록 형성되고, 상기 연결부(13)들 사이가 빈 공간으로 형성됨으로써, 열전도 성능이 저하되는 것을 방지하면서도 열전달핀(10)의 무게를 줄여 수소저장 시스템을 경량화시킬 수 있게 된다.That is, conventionally, the heat transfer fin 10 is formed in a flat disk shape to transfer heat of the tube through parts 11, whereas in the present invention, the tube through part 11 is connected to the linear connection part 13 The hydrogen storage system can be lightened by reducing the weight of the heat transfer fins 10 while preventing deterioration of the heat conduction performance by being formed so as to be connected and formed as an empty space between the connection parts 13.

더불어, 본 발명은 상기 폐공간(S) 내에 수소저장소재(30)가 구비될 수 있다.In addition, the present invention may be provided with a hydrogen storage material 30 in the closed space (S).

즉, 상기 열전달핀(10)에 형성된 빈 공간에 수소저장소재(30)가 구비됨으로써, 수소저장 시스템 내에 수소저장소재(30)의 함량을 증가시키게 되고, 이에 수소저장량을 증대시킬 수 있게 된다.That is, since the hydrogen storage material 30 is provided in the empty space formed in the heat transfer fin 10, the content of the hydrogen storage material 30 in the hydrogen storage system is increased, and thus the amount of hydrogen storage can be increased.

한편, 도 3을 참조하여 본 발명에서 튜브관통부(11)와 연결부(13)가 연결되는 구조에 대해 구체적으로 살펴보면, 상기 연결부(13)가 상호 인접한 튜브관통부(11)들 사이에 직선 또는 곡선 형상으로 연결될 수 있다.On the other hand, referring to FIG. 3, looking at the structure in which the tube through part 11 and the connection part 13 are connected in detail in the present invention, the connection part 13 is a straight line or between the tube through parts 11 adjacent to each other. It can be connected in a curved shape.

즉, 열전달핀(10)의 중앙을 기준으로 동일 반경 위치에 구비된 튜브관통부(11)들이 곡선의 연결부(13)에 의해 연결됨은 물론, 반경방향으로는 직선의 연결부(13)에 의해 연결이 될 수 있다. 또한, 이웃하는 튜브관통부(11)들끼리 직선의 연결부(13)에 의해 연결될 수도 있다.That is, the tube through parts 11 provided at the same radial position with respect to the center of the heat transfer fin 10 are connected by a curved connection part 13, as well as a straight connection part 13 in the radial direction. Can be In addition, adjacent tube through portions 11 may be connected to each other by a straight connection portion 13.

아울러, 상기 연결부(13)의 단부는 상기 튜브관통부(11)의 외주면 테두리에 일체로 고정될 수 있다.In addition, the end of the connection part 13 may be integrally fixed to the outer circumferential edge of the tube through part 11.
